[-I option] -The I option will make rsync very honest, and it will initiate data synchronization from one file. -The I option ensures data consistency. The cost is that the speed slows down because the "quick check" po

The most common commands for synchronization are as follows: rsync -avz --progress --delete rsync://rsynctest@10.211.55.11/test/ rsynctarget/ Here, rsynctest is the user name for synchronization and 10.211.55.11 is the ip address of my rsync server. Run the command and enter the p

In the source code, a perl script program named rsyncstats is released to collect statistics on log files in this format. Timeout overwrites the specified IP timeout value. This option ensures that the rsync server will not always wait for a crashed customer. Timeout is measured in seconds. 0 indicates that no timeout is defined. This is also the default value. An i
